Signal conditioning compensates for bridge sensor errors
News & Analysis  
11/24/2004   Post a comment
Offset and span are the fundamental parameters that describe how bridge sensors function, writes this TI amplifier guru in the November Planet Analog magazine. Offset is the output of the sensor without any applied stimulus. For an ideal bridge all the resistance elements would be exactly matched and the offset would be zero, he say. In reality, the offset can be a significant percentage of the sensors full scale output (FSO). A typical offset of 15 percent is common for many sensor types. Here'
IR-linked sensor simplifies temperature monitoring

It's difficult to obtain the temperature of a circuit component whose potential is several tens of volts from ground, and the job becomes harder as that voltage increases, write Maxim's applications team. Temperature measurements in high-EMI environments are also difficult, they say. A good solution for such cases is to implement a temperature probe linked to the readout location only by an infrared (IR) signal. The provision of power for the sensor can be simplified by minimizing power consumpt
